Description

Technical Field

[0001] This utility model relates to the field of splitter technology, specifically a novel splitter. Background Technology

[0002] A shunt is used to measure direct current. It is made based on the principle that a voltage is generated across a resistor when direct current passes through it. In layman's terms, a shunt is a custom resistor used to extend the range of an ammeter. A shunt has two metal terminals (used to be connected in series with the circuit under test) and two terminal blocks (connected in parallel with the ammeter terminals). The upper ends of the two terminal blocks are fixedly connected to studs and hexagonal nuts threaded onto the studs.

[0003] When measuring current, the operator needs to connect the ammeter's terminals (which are U-shaped, also known as "U-shaped lugs") to the shunt's terminals. To do this, first place the two terminals of the ammeter on the two shunt terminals, and then rotate the hexagonal nuts downwards to press them against the ammeter's terminals, thus connecting the ammeter's terminals to the shunt's terminals.

[0004] However, when temporarily measuring current or measuring current in multiple circuits under test, each measurement requires sequentially rotating the hexagonal nut downwards and then sequentially rotating it upwards. This wiring method, which uses the hexagonal nut for fixing, is inconvenient for workers and can easily lead to wear on the threads of the stud and nut, affecting the reliability of subsequent connections. Therefore, we propose a new type of shunt. Utility Model Content

[0005] The purpose of this invention is to provide a novel shunt to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel diverter includes a diverter body and two metal terminals and two wiring terminals on the diverter body. A stud is fixedly connected to the upper center of each of the two wiring terminals. A hexagonal nut is threaded onto the outer wall of each of the two studs near its upper edge. An annular pressure plate is provided between each of the two wiring terminals and the two hexagonal nuts. The two annular pressure plates are located on the outer sides of the two studs, and a moving mechanism is provided between each of the two annular pressure plates and the diverter body. The moving mechanism includes a cylinder, which is fixedly connected to the upper end of the diverter body near the wiring terminals. A connecting plate is slidably provided on the inner wall of the cylinder. One end of the connecting plate is fixedly connected to the outer wall of the annular pressure plate, and an elastic mechanism is provided between the other end of the connecting plate and the cylinder.

[0007] Preferably, a groove is provided on the inner wall of the cylinder corresponding to the connecting plate, and the groove and the connecting plate are in sliding fit.

[0008] Preferably, the elastic mechanism includes a circular plate, which is fixedly connected to the other end of the connecting plate. The outer wall of the circular plate is in contact with the inner wall of the cylinder, and a spring is fixedly connected between the upper end of the circular plate and the inner top surface of the cylinder. A pulling component is provided between the upper end of the circular plate and the cylinder.

[0009] Preferably, the pulling component includes a connecting column, which is fixedly connected to the upper center of the circular plate and located inside the spring. The connecting column slides through the upper inner wall of the cylinder, and a pull plate is fixedly connected to the upper end of the connecting column.

[0010] Preferably, the bottom ends of the two annular pressure plates are fixedly connected with annular rubber pads, and the bottom ends of the two annular rubber pads are respectively tightly fitted with the upper ends of the two terminal buttons.

[0011] Preferably, mounting holes are provided at the upper end of the main body of the splitter near both sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation of the annular pressure plate, the cylinder, the connecting plate and the elastic mechanism, when the shunt is temporarily connected to the ammeter terminal, it is not necessary to rely on the hexagonal nut to lock the ammeter terminal. The elastic mechanism controls the annular pressure plate to move up and down, which facilitates the fixing of the ammeter terminal between the metal terminal on the shunt body and the annular pressure plate, realizing the connection between the shunt body and the ammeter. The connection operation is simple, which brings convenience to the staff, and reduces the thread wear of the stud and nut, which helps to ensure the reliability of subsequent connections.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a technical solution: such as Figures 1-3 The novel diverter shown includes a diverter body 1, two metal terminals 2 and two terminal buttons 3 on the diverter body 1. A stud 4 is fixedly connected to the upper center of each of the two terminal buttons 3. A hexagonal nut 8 is threaded onto the outer wall of each of the two studs 4 near the upper edge. An annular pressure plate 5 is provided between each of the two terminal buttons 3 and the two hexagonal nuts 8. The two annular pressure plates 5 are located on the outside of the two studs 4 respectively. A moving mechanism is provided between each of the two annular pressure plates 5 and the diverter body 1. The moving mechanism includes a cylinder 6, which is fixedly connected to the upper end of the diverter body 1 near the terminal buttons 3. A connecting plate 11 is slidably provided on the inner wall of the cylinder 6. One end of the connecting plate 11 is fixedly connected to the outer wall of the annular pressure plate 5, and an elastic mechanism is provided between the other end of the connecting plate 11 and the cylinder 6.

[0019] A groove 12 is provided on the inner wall of the cylinder 6 at the location corresponding to the connecting plate 11, and the groove 12 slides in fit with the connecting plate 11.

[0020] The elastic mechanism includes a circular plate 13, which is fixedly connected to the other end of the connecting plate 11. The outer wall of the circular plate 13 is in contact with the inner wall of the cylinder 6. A spring 15 is fixedly connected between the upper end of the circular plate 13 and the inner top surface of the cylinder 6. A pulling component is provided between the upper end of the circular plate 13 and the cylinder 6.

[0021] The pulling assembly includes a connecting post 14, which is fixedly connected to the upper center of the circular plate 13 and located inside the spring 15. The connecting post 14 is slidably inserted into the upper inner wall of the cylinder 6, and a pull plate 7 is fixedly connected to the upper end of the connecting post 14.

[0022] Annular rubber pads 10 are fixedly connected to the bottom ends of the two annular pressure plates 5. The bottom ends of the two annular rubber pads 10 are tightly fitted to the upper ends of the two terminal buttons 3 respectively. Specifically, the annular rubber pads 10 have a certain elasticity and flexibility, which makes the contact between the terminal button 3 and the ammeter terminal more tight and fitted.

[0023] Mounting holes 9 are provided at the upper end of the main body 1 near both sides; specifically, the mounting holes 9 facilitate the installation and fixation of the main body 1.

[0024] Working principle: When measuring current, the ammeter needs to be connected to the shunt. First, hold the shunt body 1 with one hand and use the thumb of that hand to pry one of the pull plates 7 upward. The pull plate 7 will cause the connecting post 14 to slide upward inside the cylinder 6. The connecting post 14 will cause the circular plate 13 to slide upward inside the cylinder 6 (during this process, the spring 15 between the circular plate 13 and the cylinder 6 will be squeezed on the outer wall of the connecting post 14). The circular plate 13 will cause the connecting plate 11 to slide upward in the groove 12 on the cylinder 6. The connecting plate 11 will cause the annular pressure plate 5 and the annular rubber pad 10 on the annular pressure plate 5 to move upward together on the outside of the stud 4. At this time, the annular rubber pad 10 will leave the terminal button 3.

[0025] Then, while keeping the thumb still, use the other hand to place the ammeter's terminal on top of the terminal button 3 and hold it still. Release the pull plate 7; under the force of the spring 15, the circular plate 13 will automatically move downwards, causing the connecting plate 11 to move downwards as well. The connecting plate 11 will then cause the annular pressure plate 5 and the annular rubber pad 10 on the annular pressure plate 5 to move downwards. At this point, the annular rubber pad 10 will be tightly fitted against the upper surface of the ammeter's terminal, thus fixing the ammeter's terminal between the terminal button 3 and the annular pressure plate 5. Similarly, by following the same operation, the other terminal of the ammeter can be fixed between another terminal button 3 and the corresponding annular pressure plate 5. The operation is simple, thus achieving parallel connection between the shunt main body 1 and the ammeter. Finally, connect the two metal terminals 2 in series with the circuit under test and connect the current signal to obtain the ammeter reading.

[0026] It should be noted that when monitoring current signals for a long time is required, in order to ensure a firm connection between the ammeter's terminals and the terminal button 3, two hexagonal nuts 8 can be rotated downwards in sequence before connecting the two metal terminals 2 in series with the circuit under test. The two hexagonal nuts 8 will rotate downwards on the outer wall of their respective studs 4 until the lower ends of the two hexagonal nuts 8 are tightly fitted with the upper ends of the two annular pressure plates 5. In this way, both terminals of the ammeter can be firmly fixed between their respective terminal buttons 3 and annular pressure plates 5, which has good applicability.

[0027] It should be noted that this shunt uses an elastic mechanism to control the upward and downward movement of the annular pressure plate 5, which facilitates the fixing of the ammeter's wiring terminals between the metal terminal 2 on the shunt body 1 and the annular pressure plate 5, thus enabling the wiring between the shunt body 1 and the ammeter. The wiring operation is simple, which is convenient for the staff and reduces the wear of the studs and nuts, which helps to ensure the reliability of subsequent connections.
